To ensure the stability of the amplifier, Miller compensation was introduced between the output and the second stage transconductance. According to the design parameters and circuit, Viewlogic was used to design the required circuit diagram,Hspice was used to write simulation netlist and the whole designer was be simulated. The main parameters involved in the designer include GBW, load capacitance phase margin and supply voltage. The main contents of the report include analysis of topics, group division of labor, the overall design, theoretical analysis, simulation, summarize, feelings, ,references acknowledgements and appendix section. Analysis of topics mainly focuse on the background and application of the two-stage COMS operational transconductance amplifiers, group division of labor is about the duties and personal tasks of the team members and the completion of the individual tasks. According to personal tasks, the report has described overall project, theoretical analysis, netlist simulation and summarize in different degrees.
